Description
本発明は、心臓の僧帽弁輪の幾何学的配置(geometry)に効果がある器具を提供する。前記器具は、心臓内部の僧帽弁輪に隣接する心臓の冠状静脈の中に定位固定されるように形作られた、第1のアンカーと、第1にアンカーに固定され、第1のアンカーから心臓内に近位方向に伸びるケーブルと、第1のアンカーより近位方向の心臓内に定位固定されるように形作られて、前記ケーブルを摺動可能に受け入れるように配列された、第2のアンカーと、第2のアンカー上で前記ケーブルを固定するロックとを含む。その結果、第1および第2のアンカーが心臓内で固定されるとき、前記ケーブルは近位方向に引かれ、該ケーブルが第2のアンカー上にロックされて、僧帽弁の幾何学的配置に効果が及ぶ。
